Behavioral Design Patterns in C++ - RPN Evaluator - I

The video tutorial explains the interpreter design pattern, focusing on evaluating postfix expressions. It covers creating base and terminal classes, implementing non-terminal classes for operations like addition and subtraction, and developing a parser with an evaluation function. Tokenization and helper functions are discussed, along with handling expressions and computing results. The tutorial emphasizes code optimization and the use of C++17 features.
